Offshore Pipelines and stability assessment of Submerged Slopes under Seismic Conditions

National Technical University of Athens
National Technical University of Athens
Depending on the prevailing bathymetrical and geotechnical conditions, the integrity of offshore pipelines is threatened by potential slope instabilities that occur at the seabed or at the bottom of lakes. In addition, submarine slides are more frequent in seismic regions. The instability of onshore slopes under seismic conditions is undoubtedly a...

Artificial Intelligence in the Design of Offshore Pipelines against Geohazards

National Technical University of Athens
National Technical University of Athens
Depending on the local site conditions (i.e. bathymetry, geomorphology, geology), an offshore geohazard may have a detrimental impact on an offshore high-pressure gas pipeline during its lifetime. This fact is more pronounced in areas characterized by seismicity and the associated earthquake-related geohazards. Therefore, the design of an offshore...
